TNT is an Emacs client for AIM, AOL's free instant messaging service.
Using TNT, you can, from the comfort of your Emacs window, check
whether friends and coworkers are online, send them "instant
messages", and join them in multi-party private chat sessions. Unlike
the official AIM clients, TNT is designed to be functional rather than
pretty, easy to use rather than easy to learn. It doesn't have a
graphical user interface, fancy artwork, or other random fluff.
Instead, like other emacs extensions, it has a keyboard-driven,
text-based interface. TNT is AIM for grownups ;-).
